3.1 Installation Safety Requirements
PD drives meet the requirements of both the European LVD (Low Voltage Directive) and
EMC (Electromagnetic Compliance) directives when installed according to the instructions.
As a rule, it is recommended that you install the drive in an enclosure to protect it from
atmospheric contaminants and to prevent operator access while power is applied. Metal
equipment cabinets are ideally suited for housing the equipment because they provide
operator protection, EMC screening, and can be fitted with interlocks arranged to remove
all hazardous motor and drive power when the cabinet door is opened.
Do not arrange the interlocks to open circuit the motor phase connections while the system
is still powered as this could damage the drive.
3.1.1 Precautions
During installation, take the normal precautions against damage caused by electrostatic
discharges.
• Wear earth wrist straps.
• Include a mains power switch or circuit breaker within easy reach of the machine
operator. Label, clearly, the switch or breaker as the disconnecting device.
3.1.2 Auto-Configuration for Encoders
The PD drives recognize “smart encoders” attached to Parker PM. You can apply power to
the drive, and the drive reads all necessary motor parameters from the motor. The drive
and motor are then ready to use.
If a drive is swapped out for any reason, you can insert a replacement—the replacement
drive automatically reads the motor parameters.
3.2 System Installation Overview
The figures in this section illustrate the components necessary for electrical installation and
configuration of the PD drive. Figure xx represents the installation of models PD-04xx
through PD-35xx.
